NeOTF: Guidestar-free neural representation for broadband dynamic imaging through scattering

Y Sun and F Xia.

• We introduce NeOTF, a framework that learns an implicit neural representation of the OTF. By applying multi-frame speckle intensities and Fourier-domain prior, NeOTF robustly retrieves the system’s OTF with high fidelity and efficiency.
• Both simulations and experiments demonstrate that NeOTF achieves superior accuracy and efficiency over conventional methods, establishing it as a practical solution for imaging through dynamic scattering with spatio-temporal memory effect.

• Here, we propose a method for retrieving the optical transfer function with several speckle frames within memory effect range to image under broadband illumination. The method can be applied to image amplitude and colored objects under white LED illumination.
• The method based on the mulit-frame speckles provide more reliable results with faster convergence speed than single-shot imaging.
